Aparna Nair is one of 50 million people living with epilepsy. Here she tries to make sense of her personal experience of epilepsy by looking back at the history of a condition that is full of contradictions. It’s an illness of the brain and nervous system, yet its defining symptom, seizures, can be unforgivingly physical and happen in the most public of places. It was once associated with the supernatural but its diagnosis today is dependent on modern technology. People with epilepsy have been stigmatised by both science and religion in the past, but for Aparna, comfort and support has come from an unexpected ally.
